i have a 2001 4.4 X5
i just did the replacement upgrade from my factory 4:3 monitor to a 2005 X5 16:9 monitor/tape deck. I also replaced my MK3 to the MK4.

i bought both from an eBay seller from Lithuania who has sold a ton of these on eBay for the last couple of years. Tons of feedback. I assume that these might be refurbished or taken from crashed cars, after tons of emails and reassurance i finially beleived him that i would not have any problems.

well, its the 2nd day and the screen on the monitor is freezing, nothing happens. The actual functions work, but what ever is on the screen is stuck and frozen. Also, i am now noticing that the Radio goes silent for no reason sometimes, i can turn it off and back on and it works again, but its very annoying!

Can anyone tell what is going on or how i could fix this? The seller says it's probably not the monitor because he tested it before he sent it, and its most likely my "hardware"? As anyone heard this before?

He has been comunicating with me regularly, and is ok with me sending back the monitor for another one. But i really would like to know for sure what the problem is? I was thinking its just a bad refurbished monitor or something, but i really have no idea, please reply with any info possible, thanx!
